The practical nurse (PN) is caring for a client with a new prescription for fluticasone furoate nasal spray, a glucocorticoid prescribed for the client's nasal allergy symptoms. In reinforcing instructions about self-administration of the nasal spray, the PN should emphasize the need for the client to take which action before self-administration?

Gently blowing the nose helps to clear any mucus or debris from the nasal passages, allowing for better delivery and absorption of the medication. It also helps to ensure that the nasal passages are clear and open, allowing the medication to reach its intended target. A. Deep breathing and coughing are unrelated to the administration of nasal spray and are not necessary before using the medication. B. Checking glucose levels before and after administration is not relevant for fluticasone furoate nasal spray. Glucocorticoid nasal sprays are not typically associated with significant effects on blood glucose levels. C. Exhaling through the mouth is not a specific action required before using the nasal spray. It may be a general instruction for some other respiratory therapies or procedures, but it is not directly related to the administration of the nasal spray.
